Analytically exploiting noise correlations inside the feedback loop to improve locked-oscillator performance

Author: Sastrawan, J ; Jones, C ; Akhalwaya, I ; Uys, H ; Biercuk, MJ Date: Aug 2016 We introduce concepts from optimal estimation to the stabilization of precision frequency standards limited by noisy local oscillators. We develop a theoretical framework casting various measures for frequency standard variance in terms of ... Read more
Arbitrary quantum control of qubits in the presence of universal noise

Author: Green, TJ ; Sastrawan, J ; Uys, H ; Biercuk, MJ Date: Sep 2013 We address the problem of deriving analytic expressions for calculating universal decoherence-induced errors in qubits undergoing arbitrary, unitary, time-dependent quantum control protocols. We show that the fidelity of a control operation ... Read more
Experimental bath engineering for quantitative studies of quantum control

Author: Soare, A ; Ball, H ; Hayes, D ; Zhen, X ; Jarratt, MC ; Sastrawan, J ; Uys, H ; Biercuk, MJ Date: Apr 2014 We develop and demonstrate a technique to engineer universal unitary baths in quantum systems. Using the correspondence between unitary decoherence due to ambient environmental noise and errors in a control system for quantum bits, we show ... Read more
